The IL's first-round playoff matchups are set. West Division-champion Louisville will take on South Division-champion Durham, while Scranton/Wilkes-Barre goes against Pawtucket. The only thing left to decide is which of the latter two teams will enter the postseason as the North Division champion, and which will be the Wild Card. The Yankees currently have a three-game lead over the PawSox, and their magic number to clinch the division is two.

There is still plenty to be determined in Texas this weekend.

The winner of that race will face Arkansas in the first round of the playoffs. In the South, the first-half champion Frisco RoughRiders have a two-game lead over Midland. If the RoughRiders do indeed repeat, then the division's remaining playoff spot will go to the team with the next best overall record. Currently, San Antonio has a half-game edge over Midland in that category. The RockHounds close out the season with a three-game set against Frisco, while the Missions host last-place Corpus Christi.

San Jose has repeated as North Division champion, meaning that the two remaining playoff spots will go to the teams with the next best overall records. Stockton has already clinched one of these spots, and Modesto has a three-game lead over Visalia in the race for the remaining postseason berth. Lancaster is threatening to repeat in the South, and currently has a two-game lead over the surging Lake Elsinore Storm and a three-game advantage over the Rancho Cucamonga Quakes. If the JetHawks repeat, then Lake Elsinore, Rancho Cucamonga and Inland Empire will battle for the remaining two spots. Lake Elsinore currently leads the Quakes by three games and Inland Empire by four.

As in the California League, the two Carolina League's two first-half winners are threatening to repeat in the second half.

Second-half division winner South Bend will take on first-half Wild Card West Michigan, while first-half division-winner Lansing squares off with second-half Wild Card-recipient Dayton. Meanwhile, Burlington and Cedar Rapids have both clinched second-half playoff spots. Burlington's magic number to clinch the division is one, which means it's likely Cedar Rapids will enter the postseason as the second-half Wild Card. If this is the case, the Kernels will play first-half champion Clinton in the first round of the playoffs, while Burlington takes on first-half Wild Card Kane County.

West Virginia picked up three games on Lakewood this week, and now leads the Northern Division by a comfortable 3.5 games. The Power's magic number to clinch the division currently stands at two. Meanwhile, the GreenJackets have clinched the Southern Division, and will take on Asheville in the first round of the playoffs.

Hudson Valley can't be counted out just yet, as they trail by five in the division race and three in the Wild Card.

In that scenario, Great Falls has a three-game lead over Helena in the North, while Ogden and Casper are separated by two games in the South.

ARIZONA LEAGUE

First-half winner: AngelsSecond-half leader: Giants

The Arizona League is not broken up into divisions, which results in a simple playoff format of first-half winner vs. second-half winner. The Giants are currently at the top of the second-half standings, but the torrid Padres are just a half-game out. The two clubs play one another on Friday night, which will be the Giants' final game of the regular season. The Padres, meanwhile, are also scheduled to play the Angels on Saturday.
